BRADENTON, Fla. -- Authorities said a woman claims she found a razor blade in her McDonald's breakfast sandwich early Wednesday.

The woman was not injured but said she ordered the sausage, egg and cheese McMuffin in the drive-thru of a McDonald's in Bradenton. A police report said she claims she found the blade in the sandwich's eggs after biting into it at work.

A manager at the store told authorities that the restaurant uses razor blades, but it was unclear if they were the same type the woman claims she found. It was also unclear what the blades were used for. The manager told authorities that the only way she could see the incident happening was if someone had placed an object above the cooking area and it fell in accidentally.

Restaurant owner Cynthia Kennedy said in a statement that the public should be wary of making assumptions about the incident without more information. She said through a spokeswoman that she does not know why loose razor blades would be in the restaurant. She added that the restaurant is cooperating with the Manatee County Sheriff's Office.
